Beit known that I, OSCAR citizen of the .United States, residing at Nhitinsville, in the county of "Worcester and State of Massachusetts, have invented the following described Improvements in Bobbin-Holders.

The bobbin holder of this invention provides for the accommodation of more than a single size of bobbin without danger of the escape of the bobbin while unwindingand thereby adaptsfthe spooler in which it is employed, to be used for different varieties of work with the least trouble to the operator. i Y 1 The drawing herewith illustrates the preferred form of the invention, Figure 1 being aside elevation, with the holder rod in section; Fig. 2a top plang'and Fig. 3 an end View with the guard lug in section.

The frame of the new holder is a bracket provided with a claw 1,; and set screw,bywhich it may be attachedjto the holder-rod. 2 of the spooler, and with a bobbin abut ment 8, and also with an 'overhangingarm 4, all of which parts can be conveniently made in a single piece or casting, as shown in the drawings. The bobbin abutment 3, is

formed by a disk-shaped enlargement of the upstanding arm of. the bracket, immediately above the attachment claw 1, and provides a transversely extending surface against which the base of the bobbin'may rest. Y

The drawing shows the holder in a hori- Zontal position, but it will of course be understood that when in use on the spooler, it is supported on the holder-rod at a-slight 40 inclination which causesthe base of'the bobbin to bear against the smooth surface of the abutment. 1

The overhanging arm of the bracketis slotted for its full length and on oneside of the slotted part two lugs, 5 are'pr'ovideoi to hold the pintlefi which forms the pivotal support for the bobbin-cradle.

The latter is composed essentially of a cradle-pan 7,

.whichis skeletonized, as shown, to save weight, and two side limbs 8, which are apertured in alinement to" receive the pintle ,7 6, and joined'at the top by a relatively massive cross-piece 9 forming a counter-weight.

"Ih'e upper terminals of the limbs, above the pivotal axis, turnoutwardly or away from 1 Specification of Letters Patent.

BoBBIN-HonDER;

the pintle and serves as a means for securing the sleeve 1n difierent positions thereon;

On the opposite side from the cradlepivot, the slotted overhang is provided with twolugs 12, of which-only one-appears in the drawings, being shown in Fig. 3. These lugs are perforated to receive the ends of a wire 13, which is bent, as shown in the drawings, forming. a bobbin-guard which extends longitudinally of the holder from the bobbinabutment to a point well beyond the end of the cradle-pan. The lugs support this guard so that it may swing toward and 'from' the "cradle, engaging or resting by gravity on the bobbintherein, but outward swinging of the guard beyond the free lip of the cradle is prevented by stop portions .on' the lugs 12, oneof which stop portions is shown in section at 14: in Fig. 3.

The counterbalanced cradle and guard wire cooperate to confine the bobbin in place as the yarn is drawn from it and to maintain a substantially constant tension inthe yarn, and to this end it isnecessary that the center of gravity of the bobbin be cen-.

tralized with respect to the cradle-pan;

otherwise the jumping of the bobbin as it is rapidly unwound is apt to dislodge it from the cradle. By loosening the set screw 11 and shifting the sleeve lO one way or the other, the cradle is thereby shifted along its pivotal axis and toward the bobbin abutment, thereby bringing the pan in the de sired position and instantly adapting the .holder to be used withfany desired size of bobbin. The guide wire being longer than the range of lengthwise movement of the cradle, "will at the'same time accommodate the different bobbins without adjustment,

In the various adjustments of the bobbin cradle, a stop lug 15 in the form of a 1on It willof course. be apparent that the precise details of the support of the cradle do not form essential. features of'the present gitudinal rib serves to prevent outward swinging of the cradle-pan to-such extent as might dump the bobbin fromthe holder.
